probably be classified as belonging to the "upper part 

 of the Newer Parian" of the Government Geologists. 

 These beds are composed, in part, at least, of a dark- 

 colored and fine-grained calcareous sandstone containing 

 an abundance of small shells. No great extent of these 

 beds is exposed ; but near the Rincon, a natural savana 

 bordering on Matura Bay, the erosion caused by a small 

 stream and the wasting action of the sea have brought 

 into view a fossiliferous bed, the organic remains from 

 which may probably give us an insight into the question 

 of the age of the stratum, and may even lead ultimately 

 to a knowledge of some of the physical phenomena which 

 succeeded to the deposition of the earlier tertiaries of 

 the island. 



2. — Organic Remains. 

 The fossils found by me in the beds alluded to in the 

 foregoing section amount in number to more than ninety 

 species, and have close relationships with the recent 

 fauna, with that of the post-pliocene deposits of the 

 Antilles (Barbados, &c), and with that of the other 

 tertiaries of this island. As respects the two former 

 cases, I have been able for the most part to compare 

 specimens, but in regard to the New Parian fossils I 

 have not been able to obtain such full information as is 

 desirable. The indications furnished in the Appendix 

 to the Geological Report are very meagre ;* and after 

 a lengthened but nevertheless somewhat unatisfactoty 

 examination of the Matura fossils, I have drawn up the 

 following list : —
